Dental data in the US paints a picture that is hard to ignore, especially after US dental insurance premiums rose 5% in 2023. From 25 million Americans without dental insurance to dental care costing $171 billion every year, access and affordability ripple through visits, preventive care, and productivity. Let’s connect the dots across the biggest figures, including why so many people still skip treatment and what that means for oral health outcomes.
Key Takeaways
- 25 million Americans lack dental insurance
- Average US dental visit costs $294
- 65 million US adults visited dentist <1 year ago
- Untreated caries in primary teeth affect 530 million children worldwide
- In US, 52% of children aged 6-8 have caries experience
- Sealants reduce caries risk by 80% in molars
- In the United States, approximately 90% of adults aged 20-64 have had dental caries
- Globally, untreated caries in permanent teeth affects nearly 2.3 billion people

- Gingivitis prevalence is 90% worldwide
- Periodontitis affects 47.2% of US adults over 30
